What is Digital Signature and How to use It

But have you ever thought that these Signatures can also be bogus? There are many people who can duplicate any signature. Now here’s a little scare because if such fake signatures rob you of money earned from our hard work, it’s really a scary thing. But now you are not afraid because now we have started using Digital Signature instead of Physical Signature. That is why such a revolving work is unlikely.

Digital Signature Meaning -What is Digital Signature?

This is a technique that allows us to know the truth of anybody’s document. We can find out how much that document is Authentic or Genuine. It has been designed so that if any kind of tampering is done then it can be easily identified. This gives accurate information about the origin, identity, and status of that electronic document.

What is Digital Signature and How it works

Digital Signature is based only on Public-key Cryptography, also called Asymmetric Cryptography. It generates two keys by using the public key Algorithm such as RSA, which are Private and Public. And these two keys are mathematically linked. With the help of Signing Software to create It, the electronic form of signature to be created is made of one way hash. Then hash is encrypted with the help of Private Key. Similar encrypted hash and other related information like Hashing Algorithm are called Digital Signature. Here we encrypt empty Hash in place of the entire message so that because with the help of the Hash Function, we can translate any arbitrary input into a fixed length value which is smaller than usual. It saves time because Hashing is much faster than signing.

Hash’s value is unique if we look at its Hashed Data. If there is any change in that data, even if a character is also manipulated, then some other value will show in the result. This feature enables others to validate the integrity of the data by using the signatory’s Public Key to decrypt the hash. If decrypted hash matches, with another computed hash then it gives evidence that there is no change in the data. And if both Hash data does not match then it is possible that some changes have been made in the data, and cannot be trusted in this.

Digital Signature Example

We have a simple example of Digital Signature. When you log in to a website by logging in with your login id and password, the login id and password in it will work as a Digital Signature which verifies that you are only logging in to that website because you have to do that website I have permission to access.
